if a body moving with uniform velocity then acceleration of the body is

When is a body said to have uniform velocity?

The velocity time graph of a body in motion is a straight line inclined to the time-axis. The correct statement isSelect an answerAvelocity is uniformBacceleration is uniformCboth velocity and acceleration are uniformDneither velocity nor acceleration is uniform

The acceleration of an object is proportional to

A body starts from rest at A and moves with uniform accelerationa in a straight line. T seconds after,a second body starts from A and moves with uniform velocity Kinthe same line. Prove that the second body will be ahead of the first for a time

If the velocity of a body depends on time which is given by V = 30 + 5t2 . Then the body is undergoingA Uniform retardation B Uniform acceleration C Non-uniform acceleration D None of these
